Applications of high-energy synchrotron radiation for structural studies of polycrystalline materials.

Journal of synchrotron radiation

Poulsen HF, Garbe S, Lorentzen T, Juul Jensen D, Poulsen FW, Andersen NH, Frello T, Feidenhans'l R, Graafsma H.
PMID: 16699221
J Synchrotron Radiat. 1997 May 01;4:147-54. doi: 10.1107/S0909049597002021.

The large penetration power of high-energy X-rays (>60 keV) raises interesting prospects for new types of structural characterizations of polycrystalline materials. It becomes possible in a non-destructive manner to perform local studies, within the bulk of the material, of...

Improved grain mapping by laboratory X-ray diffraction contrast tomography.

IUCrJ. 2021 May 07;8:559-573. doi: 10.1107/S2052252521003730. eCollection 2021 Jul 01.

Laboratory diffraction contrast tomography (LabDCT) is a novel technique for non-destructive imaging of the grain structure within polycrystalline samples. To further broaden the use of this technique to a wider range of materials, both the spatial resolution and detection...

Deep learning for improving non-destructive grain mapping in 3D.

IUCrJ

Fang H, Hovad E, Zhang Y, Clemmensen LKH, Ersbøll BK, Juul Jensen D.
PMID: 34584734
IUCrJ. 2021 Jul 15;8:719-731. doi: 10.1107/S2052252521005480. eCollection 2021 Sep 01.

Laboratory X-ray diffraction contrast tomography (LabDCT) is a novel imaging technique for non-destructive 3D characterization of grain structures. An accurate grain reconstruction critically relies on precise segmentation of diffraction spots in the LabDCT images. The conventional method utilizing various...

Optimizing laboratory X-ray diffraction contrast tomography for grain structure characterization of pure iron.

Lindkvist A, Fang H, Juul Jensen D, Zhang Y.
PMID: 33833643
J Appl Crystallogr. 2021 Feb 01;54:99-110. doi: 10.1107/S1600576720014673. eCollection 2021 Feb 01.

Laboratory diffraction contrast tomography (LabDCT) is a recently developed technique for 3D nondestructive grain mapping using a conical polychromatic beam from a laboratory-based X-ray source. The effects of experimental parameters, including accelerating voltage, exposure time and number of projections...

A flexible and standalone forward simulation model for laboratory X-ray diffraction contrast tomography.

PMID: 33125349
Acta Crystallogr A Found Adv. 2020 Nov 01;76:652-663. doi: 10.1107/S2053273320010852. Epub 2020 Sep 18.

Laboratory X-ray diffraction contrast tomography (LabDCT) has recently been developed as a powerful technique for non-destructive mapping of grain microstructures in bulk materials. As the grain reconstruction relies on segmentation of diffraction spots, it is essential to understand the...

A method to characterize the roughness of 2-D line features: recrystallization boundaries.

Journal of microscopy

Sun J, Zhang YB, Dahl AB, Conradsen K, Juul Jensen D.
PMID: 27896802
J Microsc. 2017 Mar;265(3):313-321. doi: 10.1111/jmi.12501. Epub 2016 Nov 29.

A method is presented, which allows quantification of the roughness of nonplanar boundaries of objects for which the neutral plane is not known. The method provides quantitative descriptions of both the local and global characteristics. How the method can...

Boundary migration in a 3D deformed microstructure inside an opaque sample.

Scientific reports

Zhang YB, Budai JD, Tischler JZ, Liu W, Xu R, Homer ER, Godfrey A, Juul Jensen D.
PMID: 28667251
Sci Rep. 2017 Jun 30;7(1):4423. doi: 10.1038/s41598-017-04087-9.

How boundaries surrounding recrystallization grains migrate through the 3D network of dislocation boundaries in deformed crystalline materials is unknown and critical for the resulting recrystallized crystalline materials. Using X-ray Laue diffraction microscopy, we show for the first time the...

Direct observation of nucleation in the bulk of an opaque sample.

Sci Rep. 2017 Feb 14;7:42508. doi: 10.1038/srep42508.

Remarkably little is known about the physical phenomena leading to nucleation of new perfect crystals within deformed metals during annealing, in particular how and where volumes with nearly perfect lattices evolve from structures filled with dislocations, and how local...
